The Rolls-Royce Phantom III Drophead Coupé is a British handmade luxury car manufactured by Rolls-Royce that debuted at the 2007 North American International Auto Show in Detroit, Michigan, on 7 January 2007. It is based on the 2003 Rolls-Royce Phantom and has styling heavily derived from the 100EX, a concept car shown to celebrate the company's centennial in 2004. In 2015 it was the most expensive Rolls-Royce model at $533,000. Several Drophead Coupés were used in the 2012 Summer Olympics closing ceremony.
